Note 1. See notes on page 38.
2. Braking is not activated at deceleration stop. It coasts to a stop.
3. Use MC or MCX of delay release type for restart operation after momen-
tary power loss.
4. Frequency setting resistor is not required for the use of digital operator's
set value as frequency reference.
